Hi, just bought a Luckfox Lyra Ultra RK3506B and I am having a problem using a USB sound device. From research on the internet all I can find is that the USB sound has to be enabled in the Kernel but I am not sure how to do that. Any advise or help would be greatly appreciated. With the command lsusb I get back Bus 001 Device 003: ID 0d8c:0012 C-Media Electronics, Inc. USB Audio Device.
Kind regards
Steve

Hello, you can execute "./build.sh kernelconfig" in the SDK to search for "SND_USB_AUDIO" and enable the support. By default, it will be added to the rootfs in the form of a module. You need to fully compile the entire system and re-flash it.

The USB sound card function is controlled by the kernel driver and is independent of the rootfs used. This method can also be used even when using a non-buildroot system.
